Classification component 10 has a propulsion system 41, and in shown embodiment, this system is a linear motor propulsion system.Linear motor propulsion system 41 comprises one or more linear motor main parts 28 and a plurality of linear motor auxiliary members 63 on lath.In shown embodiment, the linear motor auxiliary member is included in the magnetic sheet 64 of the inside 42 of some or all lath 20, and these magnetic sheets combine (Fig. 2) with the lower wall 36 of lath.Magnetic sheet 64 is positioned in the inside 42 of contiguous main part 28.Main part 28 is closely kept apart with lath 20, forms a lath gap SG between a cooresponding surface of the surface of main part 28 and lath 20, and between the surface of main part 28 and magnetic sheet 64 a formation magnetic gap MG (Fig. 3).When auxiliary member 63 process main parts 28, the outshot of magnetic sheet 64 has a magnetic interaction face MI on main part 28, perhaps opposite.In order to make magnetic gap MG reach minimum, can be by the transverse arresting apparatus that inside outshot 84 and passage 48 constitute in the outside of magnetic interaction face MI.Among the embodiment, horizontal stabilizing device is close to rear wall 40 shown in figure 2.Among another embodiment shown in Figure 3, the transverse arresting apparatus adjacent front wall 38 of lath 20a.Those skilled in the art can oneself imagine other position.Among another embodiment shown in Figure 26, promoting slide block and lath all has traditional configuration, but they also are provided with the magnetic sheet 64 in lath.Can between the front and back of slide block, locate this transverse arresting apparatus, in the front and back of transverse arresting apparatus linear motor magnetic sheet 64 is set, as shown in Figure 26.Transverse arresting apparatus also can be placed on the upper wall 34.In fact, magnetic sheet 64 can be divided into two magnetic sheets, make transverse arresting apparatus between two magnetic sheets.Alternatively, disclosed slide block and lath can be provided with a magnetic sheet of the base of the outwardly directed outshot that is positioned at lath in US Patent 5127510, and this base constitutes the part of transverse arresting apparatus.In such embodiments, can increase the size from front to back of base of the outshot of transverse arresting apparatus, so that adapt to auxiliary member 64, as shown in Figure 26 b.Best, transverse arresting apparatus is basically in the outside of magnetic interaction surface MI.
Magnetic sheet 64 is positioned in the accommodation section section 62 of lath 20.By the fixing magnetic sheet 64 in the inside of corresponding lath.Can not need fastener like this, must after magnetic sheet being positioned in the lath, pass lath and apply these fasteners dividually, engage with hole in the magnetic sheet.A kind of mode by lath internal fixation magnetic sheet provides the accommodation section section 62 that has one or more ratchets, with Reference numeral 65 and 66 these ratchets is shown in the drawings, and they live magnetic sheet 64 by the lath internal fixation.The relative size of magnetic sheet 64 and lath 20 provides a kind of force fit between magnetic sheet 64 and ratchet 65 and 66.Yet, can use the internal fixation magnetic sheet 64 of other technology by lath 20, such as by wall 34,36,38 or 40 is out of shape towards magnetic sheet, as illustrated in Figure 25, perhaps by using insert, such as plastic insertion piece or analogue, in order that auxiliary member and lath are locked mutually.Alternatively, magnetic sheet can be fixed in its position, such as passing through welding, bonding or similar fashion.
Linear motor main part 28 advantageously can be positioned in the endless belt 12 (Fig. 9).Linear motor main part 28 can the adjacent rings band top stroke 13, and by following driving lath 20.Main part 28 can be above bottom run 14, and by top driving lath 20.The linear motor main part 28 of adjacent top stroke 13 can be positioned at the position that steering assembly 16 is not set, such as between steering assembly 16 (Figure 15).This makes the linear motor main part can be close to endless belt 12, disturbs promoting not turning to of slide block 26.Although shown main part 28 should be understood that on the cross central line of band they can be by horizontal centerline offset, and can interlock.Also more than one main part can be set abreast, such as driving more than one auxiliary member for each lath.
Supporting track network 19 is by following support foot stroke 14.Therefore, the weight of bottom run 14 is pressed in bottom run on the supporting track network.The linear motor main part 28 of the lath of driving in bottom run 14 provides thrust or the progradation power FT that is propulsive with 12, and provides one to be tending towards attracting the motor magnetic sheet and therefore attracting the attractive force FA of lath towards the linear motor main part.Design auxiliary member 63 in one way and control the linear motor main part 28 of adjacent bottom stroke 14 in one way, this mode is restricted to directed force F A the degree that can not make bottom run 14 raise, leave supporting track network 19 significantly.Reduce any noise from lath 20 so significantly, when main part was crossed in the lath motion, directed force F A raise this lath, drops on subsequently on the supporting track network 19.
Classification component 10 comprises a propulsion control system 500.Propulsion control system 500 is closed loop propel system that are used for endless belt 12.Propulsion control system 500 comprises a belt sensor 502, and it provides an output signal 503 to linear motor controller 504.Propulsion control system 500 also comprises linear motor driving device 506, and each linear motor driving device provides big electric current at mouth 508, and electric current is offered corresponding linear motor main part 28.Linear motor driving device 506 is traditional motor controllers, and such as frequency-conversion drive apparatus, these actuating devices can provide energy to corresponding linear motor main part 28.Such linear motor driving device commercial can be by multiple source such as Siemens A.G., Mitsubishi, Ltd., and similar company obtains.Each linear motor driving device receives an input 510, and the output of linear motor driving device 506 is set up in this input, thereby determines to export 508 character that are applied to the excitation current on the linear motor main part.Traditionally, input 510 is variable signals, and such as an aanalogvoltage, it can be between 0 and 5 volt or between 0 and 10 volt or with similar interval variation.The frequency of the output of the size of aanalogvoltage control linear motor driving device 506 makes at the voltage values of 510 inputs greatly more, and cooresponding linear motor driving device 506 is high more in the frequency of 508 output.Addressable interface 512 is set up input 510.Interface 512 can be by linear motor controller 504 individually addressing on a digital interface 514.Digital interface 514 makes linear motor controller 504 individually to carry out addressing to each interface 512, in order that set input 510 for relevant linear motor driving device.Digital interface 514 can be a traditional bus, such as CAN, a LAN, Ethernet, and perhaps other known traditional bus system or client bus system.
Passing through of each lath 20 of belt sensor 502 perception, thus will offer linear motor controller 504 about information to export 503 with 12 speed.In order to realize such perception, belt sensor 502 can be a proximity transducer, such as inductive proximity sensors, optical pickocff, sonac, microwave remote sensor or similar sensor.Gap between the belt sensor 502 perception laths, but the also additionally motion of perception lath directly contact with lath such as passing through, perhaps similar approach.Belt sensor 502 also can have the ability of the single lath of identification.For example, belt sensor 502 can comprise a Magnetic Sensor, such as a Hall effect sensor 572, and the one or more magnets of its perception in one or more laths 20.By the lath of confirming pass through a specific time, such as being marked as leading lath, with corresponding by the lath of determining with the integration of 12 speed, provide a confirmation to controller 504: lath speed sensor 560 is suitably operation.
Linear motor controller 504 will be delivered to each addressable interface 512 about the digital signal of digital interface 514, in order that determine its output, and determine the speed of cooresponding linear motor driving device thus.This layout makes the ability of linear motor controller 504 can control the output of linear motor driving device 506.In some applications, classification component 10 can have very long length, has the hundreds of foot, adopts the linear motor propulsion system to be beneficial to.Digital signal at each linear motor controller has reduced the adjustment of traditional approach of essentiality do to(for) the analog input that is input to linear motor driving device 506 to this conversion of analog signal, and these actuating devices and linear motor controller 504 leave quite far.Also have, propulsion control system 500 makes each linear motor driving device 506 individually to control.For example, quicken or condition that load is heavier under, linear motor controller 504 can provide energy to whole or most of linear motor driving devices 506, so that to providing enough propelling thrusts with 12.Under other condition, such as under the lighter condition of load or at the stabilized conditions run duration, linear motor controller 504 can so that the output 508 that the relevant linear motor driving device 506 of one or more addressable interface 512 indications offers relevant linear motor main part 28 with the thrust that reduces or there is not thrust corresponding fully.Those skilled in the art can oneself imagine other example of using propulsion control system 500 individually to control linear motor driving device 506, and wish all these examples are included in here.
Propulsion control system 500 comprises a control program 520 (Figure 16).In shown embodiment, based on linear motor driving device 506 executive control programs 520 of microcomputer.Control program 520 begins at 522 places, and at 524 places with the initialization of a control loop filter.This control loop filter comprises velocity filter or allied equipment, and it is set is in order to limit the response for the quick fluctuating in the output of belt sensor 502.A window filter is applied in the speed input subsequently such as the speed that calculates by reading output 503 and 526 controllers with 12, and at 528 places.This window filter is can not make unsuitable reaction to the flip-flop of the tape speed of belt sensor report for the PID part that keeps loop.For example, this window filter PID part of having reduced control piece is made the possibility of excessive response for tape speed.This can by will be in window the fwd numerical value of some average and realize.
Filter is sized to for loop and provides response.If the speed of sample changes,, keep the time constant of filter constant such as because the change of system load will change the speed of sample.Determine at 530 places whether filter can the automatic compensation size.If can, redefine size at 532 place's filters.Can be so that the size adjusting of filter becomes the delay make in closed loop control to remain minimum and is foreseeable.This is because the reduction of the responding ability of speed control has reduced control piece the speed of being with to be remained on an ability in the narrow permissible range.Calculate the error of band at 533 places, calculate work order at 534 places subsequently.Work order is the voltage that produces at 510 places, to select a special output of linear motor driving device 506, changes in order that realize desired thrust.If desired, this also can comprise a scaling factor, in order that adapt to the special parameter of the linear motor driving device 506 that is adopted.Control piece 502 is delivered to single addressable interface 512 by digital interface 514 with an order at 536 places subsequently.
Control program 520 is determined at 538 places in order to ensure loop suitably and can repeatedly adjust, and the adjustment of loop will be carried out how soon.If the speed control loop is delayed and/or is slowed down, control program 520 can be notified upper class control piece (not shown).Control piece 520 determines whether and need state machine 540 be upgraded at 542 places subsequently.Determine whether to realize a kind of function that deposits in subsequently at 544 places.If can realize depositing in function, deposit data in 546, be the work order of unit such as tape speed, tape speed error, with the hertz, perhaps class likelihood data.This function system that makes that deposits in can monitor how sorting machine responds to the variation that changes such as load or speed.This makes that also control piece can the accumulated history data, detecting error at the some parts of classification component, and the excessive resistance that produces such as wheel bearing, perhaps class likelihood data.Whether control piece drops on the outside of control loop parameter in 548 work of determining control loop subsequently.If like this, the output of addressable interface 512 is set to " safety " state at 550 places, notifying operation person faulty condition therewith combines." safety " state can be the zero velocity state, perhaps can be the state that speed reduces.If determine mode of operation at 558 places not in the outside of control loop, control piece returns 226, visits the lath sensor once more at this, and carries out control loop again.
State machine 540 is determined the state of control loop, and sets up the parameter limit of closed loop control according to its state (Figure 17).State machine 540 comprises a halted state 552, an acceleration mode 554, at this state, the linear motor propulsion system will be with acceleration, and an idling mode 556 is at this state, speed for band is not done any adjustment, and a deceleration regime 558, at this state, the linear motor propulsion system will be with deceleration.For every kind of state 552-558, the error that all will determine speed whether in acceptable scope, if not, control piece moves to a different state, so that realize appropriate functional.
Belt sensor 502 comprises a proximity transducer 560, and its form is a tuning lc circuit, and oscillator 562 offers this LC circuit (Figure 18) at oscillator circuit 564 with the square wave of a vibration.If wishing provides oscillator signal by an external source, just oscillator circuit 564 is connected with an outside input 503.If like this, can will form the parts of oscillator 562 by removing in the circuit.Oscillator circuit 564 offers proximity transducer 560, and offers an exclusive OR computing (EXCLUSIVE OR) circuit 566.By an amplifier 568 output of proximity transducer 560 is offered other input of exclusive OR arithmetical circuit 566, integration is carried out in the output of 568 pairs of exclusive OR arithmetical circuits 566 of an integrator.Provide the output of integrator 568 at 570 places, as a lath detection signal.By under the condition of the metal surface that is with or without each lath, changing its resonance frequency, make this proximity transducer 560 work, cause the phase shifts between the input of exclusive OR arithmetical circuit 566.This phase shifts causes the variation of output, and integrator 568 carries out integration to this output, thereby makes output 503 along with there being gap or very close to each other and change between the lath.
Belt sensor 502 can additionally comprise a band means of identification, and its form is a Magnetic Sensor 572.This sensor 572 can be a Hall effect sensor, or the sensor of other type, such as reed switch or similarity piece that can perception magnetic field.Magnetic Sensor 572 detects one or more permanent magnets, perhaps arctic, perhaps South Pole, perhaps north and south poles both.One or more magnets like this can be arranged on a quilt note and do in the lath of index lath, perhaps are arranged in the more than one lath, in this case, can in each lath magnet be set in the mode of encoding with a kind of layout of uniqueness.Provide the output of Magnetic Sensor 572 at 503 places, as an output.
As the front is narrated, belt sensor 502 will offer the linear motor controller 504 with the identification campaign of one or more index lath along with a signal with 12 rapid change.When returning, linear motor controller 504 provides digital signal, and these signals are the inputs that separate to addressable interface 512, in order that control corresponding linear motor drive 506.The control program 520 operation closed loop control algorithms that controller 504 or other computing machine are carried out are so that keep the tight adjusting with 12 speed.In shown embodiment, with normal speed with plus or minus percent 2.5 or variation accommodation zone 12 still less.The state of running condition machine 540 monitoring linear motor propulsion control systems, and guarantee by for every kind of different setting state error the speed of being with being realized suitable control.Propulsion control system 500 control linear motor controllers 504, its mode are to make the desirable speed of linear motor main part operation near it, and are no more than the attractive force on lath.
As traditionally and as skilled in the art to understand, the output of frequency conversion linear motor driving device 506 is changing between such as 120 hertz such as 0 hertz and highest frequency, and obtain thrust output with cooresponding linear motor main part 28, the variation of this thrust is the function of the frequency output of linear motor driving device.As also having known in this area, the relation between this frequency and the thrust is belt-shaped slightly curve, makes that the intermediate value place between maxim and minimum value produces maximum thrust (Figure 19).In shown embodiment, control program 520 is in a side of the maximum thrust value of frequency curve or the output of opposite side control linear motor driving device 506.Traditionally, use the front side of curve F, between 0 hertz and maximum thrust.Yet should be susceptible to control program can promptly, surpass the frequency of acquisition maximum thrust and the frequency higher than this value for frequency values in the rear side B operation of thrust with the curve of hertz.When in this rear side B of curve operation, obtain even higher thrust magnitude FT is possible for attractive force FA less between linear motor main part 28 and lath, thereby reduced the possibility that the lath in the down stroke 14 that motor makes supporting track network 19 raises.
Control program 520 comprises a target velocity, and makes comparisons with the motion of lath, calculates error term, and uses some approximate signals that refer to that generation moves linear motor driving device.Control loop is proportion integration differentiation (PID) controller of a numeral, but can adopt other Closed loop Control, such as the simulation control loop, and similar control loop.Because require even littler gap, wish to make that transmitting the surface by one transmits the minimum that is changed on surface to another, such as by an introducing or feeding conveyor the minimum that is changed to classification component.The variation of any speed may increase or compressed articles between the gap.For example when conveyer has full wrapped load and emits many packages suddenly, velocity variations may occur, the load of flip-flop subsequently may cause the change of speed.Closed loop propulsion control system of the present invention has been avoided the problem with the conventional open-loop actuating device that is used for classification component.Classification component 10 can comprise an idling pattern, wherein, if do not detect package in the upstream of classification component, the speed of classification component can be reduced to the speed of an attenuating, such as half or similar value of the speed of being reduced to.Can reduce wear like this and expenditure of energy, and can avoid when article offer sorting machine again, speed need being improved, turn back to line speed for the national games.
Further determine: also can select design parameters, its mode makes that attraction force is minimum, makes thrust forward reach maximum simultaneously.In shown embodiment, classification for width between about 1.2 meters to about 1.6 meters brings, determined: the desirable thrust FT of following parameter generating, and can not produce the too high attraction force FA that lath in the down stroke 14 that may raise significantly leaves their supporting track.
Auxiliary member width (transmitting the width of the transverse direction on surface): about 160 millimeters to about 180 millimeters.
Auxiliary member length (transmitting the length of the longitudinal direction on surface): about 110 millimeters to about 120 millimeters.
Thickness: about 4 millimeters to about 6 millimeters.
Magnetic gap (MG): about 8 millimeters to about 9 millimeters.
Lath gap (SG): about 2 millimeters to about 3 millimeters.
In shown embodiment, 7.5 to 8.5 amperes electric currents are offered the linear motor main part.As an example, the interval of motor main part can be approximately per 8 meters of conveyer length.As an example, may comprise 20 to 25 linear motor main parts like this for 120 meters sorting machines.However, it is to be understood that these design parameterss can be along with other parameter change of load, speed and band classification component.
The linear motor propulsion system can be a non-synchronous type, and wherein magnetic sheet 64 is made by a kind of magnetic material of conduct magnetism.The example of such magnetic material comprises carbon steel, iron and other known such penetrable material.In shown embodiment, this plate is made by cold-rolling steel.Alternatively, the linear motor propulsion system can be a synchronized model, can be permanent magnet for this system magnetic sheet 64, such as ferrite, aluminium nickel cobalt or analogue.For a synchronous system, magnetic sheet typically can be installed on the lath, rather than on the in-to-in lateral surface, makes that the wall of lath is not the part of auxiliary member.By make magnetic sheet become lath wall a part or by on the outside face that magnetic sheet is installed to lath, can realize above-mentioned installation.The moyor of this synchronous propulsion system is than asynchronous propulsion system height, and this system does not influence in the situation of the article character that is classified or exists in the situation that does not influence other metal under the condition of classification component in the existence of permanent magnet and uses.Certainly, the classification component that produces a kind of synchronous and asynchronous linear motor system that combines may be wished.For example, by in the magnetic magnetic sheet of lath in-to-in outside, producing thrust, main part below the top stroke of band can be used as synchronous linear motor operation, and by produce thrust in the magnetic sheet of the penetrable magnetic of lath in-to-in, the main part above the bottom run of band can be used as asynchronous linear motor operation.Can make the motor below the stroke of top can guarantee higher thrust like this, and need be with respect to attraction force, and make the motor above down stroke can apply enough thrust, so that the lath in down stroke keeps motion, keep sizable thrust on the entire belt and not be used in.The present invention is as an advantage of a synchronous linear motor propulsion system operation at least in part: the magnetic sheet of magnetic can be on the side relative with transmitting the surface of lath.This can reduce significantly from the threat for the article that are classified of the magnetic field of magnetic sheet.
Can see for fear of the lath in bottom run is raise to the control of linear motor main part with reference to figure 20a and 20b.These illustrate space rate, the lath speed of each motor and are applied to relation between the frequency on the linear motor main part.Leave the lath supporting member in bottom run in order to prevent the lath rising, motor speed deducts lath speed (being also referred to as slippage) must be enough high, perhaps, must sufficiently reduce motor current, to avoid surpassing a specific attraction force for lower slippage numerical value.In other words, the linear velocity of motor must be than the linear velocity height of lath, makes that at least the linear motor in bottom run can not move near under the synchronous speed.Yet it may be undesirable making slippage drop to too low.What this for example may require when reducing tape speed power reduces not too soon, otherwise trembling of lath may occur.
